T0 ALL WHOM IT MAY GONCERN: Y
Beiteknown that 1, DEXTER AVERY, of Westfield, in the county of Harnpden, and State of Massachusetts, have invented a new and improved Carrier for Breitling-Machines; endl do'hereby declare that the following is a full, clear, and exaet'descriptiou thereof', wine-huilt enable others'shilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which-'- Figure 1 represents a side view, partly in section, oi my improved carrier.
Figure 2 is a horizontal sectionaly view ci' the same, taken on the plane of the line x 1.
Similar letters of reference indicate corresponding parts. t
This invention relates to a/ne'w carrier for braiding-machines, theobject of which is to produce the required tension ofthe threads, to protect` the spring (which-keeps the spring tense)frou1 wear, and tb obtain acomplete and eicctive carrier in the simplest and least expensive manner.
The invention consists in the manner ot guiding and protecting the spring, which works in a tubular holder, and around the hook-rod, to which the thread is attached; also in a new manner of guiding the sliding catch, by which the intermittent motion ofthe bobbin is produced, and in the general combination of all the parts, as will bc hereinafter more fully described. j
A, in the drawing, represents the spindle, around whichthe bobbin B turns, said bobbin resting .upon a dange, a, that is formed on the spindle. The spindle A is tub'ular, as shown, and has two shoulders, 6 c, formed within its bore, so asfto have three variations of bore, as shown in tig. 1. The uppermost end ofthe bore is the narrowest, and the lowermost thc widest, as shown.
The spindle or carrier A has a suitable elliptic or other external shoe, d, which is between two danges, aa', and which moves in suitable guides that are on the frame of the machine.
From the ange a projects, upwards, a rod, e, which is parallel with the tube A, as shown.
Within the tubcIA is arranged a rod, C, which has ahool:` at its upper end, and a head,f, at its lower end. A spiral spring, D, is arranged within the tube A, around the rod C, and between the upper shoulder b and the head fot` the rod, as is clearly shown in fig. 1. i
The outside of the spring D only touches-,the tube A in that portion'of the same which is between the shoulders b and e.
Thelower part ofthe tube is too wide for the-spring toreach it, and just large enough for the head f to `play in. The spring is thus fully prot'eetcd, and cannot wear against the tube, being completely guided by the rodO. From the head f projects a lug, g, which iits through a slot in the lower part of the tube, and which i serves as a handle to more the rod C up, to'havc itshook threaded. 'lhe bobbin B, upon which the thread is wound, has la: ratchet-formed at its upper end, as shown, and as usual.
Upon the rod a slides a slotted tube, E, from which an arm, z, projects, which arm rests upon the ratchetend of the bobbin. AA pin, t', projecting from therod e, itsthrough the slotl in the tube E, and prevents the same from turning, so that should the thread jbreak, the arm h may not fly round and strike the thread on another carrier, thereby also breakingv the same.
The end of the thread is, `fiornthe bobbin, brought through an eye, j, in the rod e,'thence laid over the forked end of the rod c, brought through a loop in the end of the arm z, and then through the hook on the upper end of the rod C. i
The thread is then drawn once more through the eye in the arm 7i, and finally through the upper end of the tube A, asis clearly indicated by red lines in.g.`1.
The spring D vkeeps the thread always tense, butstill allows the rod C to be drawn up by the same. When the thread is pulled by the action of the machine, the bobbin cannot turn, as it is held by the arm i. The arm C will, therefore, be drawn up until its hooked end strikes the end ot' the arm 7i, when the latter will be raised out ofthe ratchet so as to liberato the bobbin. Thereqircd quantity of thread is then taken from'thebobbin, the motion of which is again stopped by the arm h falling into the next tooth of the ratchet.
The upper portion of the tube A, between the upper end of the bobbin and the extreme upper end of the tube, is laid open, so as to facilitate the threading ofthe hook, andvto enable the end of the arm 7L to be above the hook C.
Having thus described iny invention, what I claim as new, and'desire to -secure by LetterslPatent, is
The hollow spindle A, spring D, and hook-rod C, in combination with the rod e, sleeve E, and arm h, all
made and operating substantially as and for the purpose flieieinshown and described. lDEXTER AVERY.
